1991 4.0 I had the head rebuilt and when I took the rockers/pivots/rods I put them all in a bucket and mixed them up. The engine builder told me they can go back in mixed up just to make sure the ridges on the pivots are matching the rockers. My question is do they have to go back in a certain order? Reason I ask is not all the rides on the rockers are facing the same way. They look like this \/ /\. The rods were in good shape and the wear on the pivots/rockers was normal. They bead blasted them at the shop and cleand it all up they look brand new otherwise I would have just replaced them.

 

Melling or Sealed Power will run you about $2-3 each.

I'd replace them, specifically since they were bead blasted.
